Contracts

flashloan contract addresses

InstaFlashAggregator

flashloan()

Sends the requested amounts of assets to the contract which called it, passing the included params, using the passed route. If the flash loaned amounts + fee is not returned by the end of the transaction, then the transaction will revert.

function flashLoan(         address[] memory tokens,            uint256[] memory amounts,        uint256 route,        bytes calldata data,        bytes calldata instaData    );

getRoutes()

Returns an integer list of available routes.

function getRoutes() public pure returns (uint16[] memory routes);

InstaFlashResolver

This contract can be used to get data from the flashloan aggregator which can be helpful in deciding the route through which user wants to take flashloan. The flashResolver has the following functions:-

getRoutes()

This function returns all routes that are supported by FLA (Flashloan Aggregator) for that particiular chain.

function getRoutes() public view returns (uint16[] memory)

getBestRoutes()

This function returns the bestRoutes (can be more than 1), the best fee in BPS (1 BPS = 0.01%) and the bestData . The best routes are found considering the tokens availability, amounts of tokens for flashloan, and the fee.

function getBestRoutes(address[] memory tokens, uint256[] memory amounts) public view returns (uint16[] memory, uint256, bytes[] memory)

getData()

This function internally calls getRoutes() and getBestRoutes() functions and returns the compiled data.

function getData(address[] memory tokens, uint256[] memory amounts) public view returns (uint16[] memory, uint16[] memory, uint256, bytes[] memory)

Receiver Contract Interface

The receiver contract must follow the below interface to use the flashloan aggregator.

interface InstaFlashReceiverInterface {    function executeOperation(        address[] calldata assets,        uint256[] calldata amounts,        uint256[] calldata premiums,        address initiator,        bytes calldata data    ) external returns (bool);}
